BusinessWire: The upcoming LG V30 smartphone is said to have camera module with F#1.6 lens, said to be the brightest in smartphones. I wonder what is the effective aperture of the pixels in the sensor and whether it makes use of the so bright lens.

Large aperture is easy and cheap to make for small sensors, but it has to be seen in context with the sensor size. This aperture increase is probably done to reduce sensor size, which likely counterweights the noise improvement.

Regardless of sensor size a downside of large apertures are low contrast and lack of sharpness. (Not to be confused with depth of field, that's a different topic).
